To all whom, it may concern.-

. Be it known that I, JosErH WYBAUW, a subject of the King of Belgium,residing at Brussels, in the Kingdom of Belgium, have invented certainnew and useful Improvements in Gas-Meters for Registering Separately theConsumption of Gas by Night and by Day, (for which I have obtainedpatents in Belgium January 23, 1885, No. 67,633, June 17, 1885, No.69,310, and August 7, 1885, No. 69.818; in France, February 10, 1885,April 1, 1885, and October 19, 1885, No. 166,960; in Germany, May 4,1885, No. 35,274, and in England, May 6, 1885, No. 5,564,) of which thefollowing is a specification.

In order that my invention may be fully understood,l will proceed todescribe it with reference to the accompanying drawings, in which-Figure 1 is a side elevation of that portion of a meter to which myinvention in its pre ferred form is applied. Fig. 2 is an elevation indetail, showing a modification in which means for coupling the primarydial-wheels instead of the shafts are shown. Fig. 3 is an elevation indetail, showing another modification, in which the primary dial-wheelsare coupled by means of an endless screw shaft. Fig. 4 is an elevationin detail, showing another modification,in which thecouplingshown in thefirst modification is operated by means of a cam-dia1 connected tosuitable clock-work. Fig. 5 is an elevationindetail,showingamodification in the form of weighted lever. Fig. 1 is a detail of thebell-supporting device, showing the position it assumes when thrown out.Fig. 1" is a detail of the same showing the device in operativeposition. Fig. 1 is a detail of the same showing the device in normal orinoperative position.

The gas-meter hereinafter described has for its object the registeringof the amount of gas consumed during the day and the night,respectively, the mechanism being actuated by means of variations in thegas-pressure exercised by the gasworks itself. I

To this end the ordinary gas-meter is provided with a second dial, E,placed above the ordinary dial, D. The latter indicates the to- (Nomodel.) Patented in Belgium January .33, 1885, No. 67.633, June 17,

tal consumption, while the upper dial indicates the day or nightconsumption. The ver tical shaft F, which gives motion to this upperdial, is placed in connection with the prolongatioh yof shaft G of thelower dial, and may be connected to this shaft by means of a connectingcoupling or muff, H. This latter carries a pin, I, which, when coming incontact with cross-bar or pusher K, is urged forward by it, andaccordingly the two dials are set to mo tion together.

lowered by means of a lever, O, pivoted at L. This lever extends to theback partof the meter, where it supports a bell, A, plunging inglycerinc or mercury contained in a reservoir afiixed to the meter. Theinterior of the hell by means of a small pipe, B. The whole attachmentis protected by a cover, preventing access thereto from outside.

The working of the apparatus is as follows: Vhen the gas-works gives theevening pressure,the bell A is raised, the coupling or muff H islowered, the pin I comes in the horizontal plane of the cross-bar orpusher K, and when the gas entering the meter imparts to the shaft G arotary motion with the dial D the shaft Fturns similarly and thedialindices of the dial E are set in motion. The pressure being lowered,the bell descends, the shafts are disconnected, and the dialEremainsstationary, while the motion of Dis continued. The high pressurebeing generally produced at night, the evening consumption is registeredon the upper dial. By subtracting the number from the total registeredupon the dial D the consumption made under the low pressure is obtained; but as according to the consumption the pressure of gas may incertain (USPS be lowered enough to prevent the bell from being kept upthe whole evening, a pawl, R, is provided, the purpose of which is toprevent the bell from being lowered before the requisite moment. Thispawl may be constructed in several ways. The drawings show a pawlintended to prevent this lowering during the whole night. When theevening pressure is set, the bell rises until it strikes the weight I?The connecting coupling or muff is lifted or communicates with aninlet-pipe for the gas on a lever, N, having supporting-arm K andpivoted at M. The pawl R falls below the tooth r, and the bell is soprevented from descending. In the morning the gasworks gives a higherpressure during one moment, so as to lift the bell with the weight P.The heel m pushes against the short arm of the pawl R and throws out thelong arm upon the wall of the reservoir. The pressure being immediatelylowered, the bell falls down, the click n strikes the short arm, and thepawl falling, its long arm comes to normal position over the tooth r. Itremains in this position until, the bell being lifted again in theevening by the pressure, that arm falls again below the tooth 1' untilmorning, and so on. Another disposition of the pawl is shown in Fig. 5.The bell being lifted, the weight P takes a vertical position, with itssupporting-lever N, having short arm N, bearing on the bell. The leverbears against a stop, and exercises no weight upon the bell. In orderthat the bell could be lowered, it is necessary that the pressure shoulddecrease more or less, and this generally happens about midnight at themoment the pressure in town is lowered. The connection of the two dialscould also be obtained without any hell by the subscriber himself bymeans of a key; but in this case the motion should be shown outside bymeans ofa manometer, or a pipe being filled with gas and affordingcontrol. The meter could also be provided with two exit-pipesone for theheating-gas and the other for lighting purposes. This latter is providedwith a cook, the opening or shutting of which causes the connection ordisconnection of both dials. The subscriber cannot thus use the gas forlighting purposes unless the two dials are connected.

The bell may be replaced by a membrane or a flexible partition. Theconnecting coupling or mufl' may be replaced by any of the dispositionsshown, Figs. 2 and 4, where an auxiliary wheel, H, mounted on alever, 0,connects with both primary dial-wheels O Q at the moment the point 0 islowered by the lever O. The principal dial may also be dispensed withand the endless screw H, Fig. 3, be main tained, which gears withfone orboth the primary wheels of the dialsone for the day and the other forthe night consumption of gas. The upper primary dial-wheel is supportedon the short arm of a lever, 0. Finally, the connection may be obtainedby means of a clock-work. The shaft S, Fig. 4, of the clock, making onerevolution in twenty-four hours, carries an eccentric or cam dial,coming in contact with a screw, e, on the long arm of the lever L. Asthe eccentric comes in contact with the end of screw e by its side'oflongest radius, the auxiliary wheel H does not connect with the lowerdial-wheel. When the shortest radius side of the eccentric is in frontof screw 6, the arm L rests on the stop Z and the end of the screw doesnot touch the eccentric. Both dials are then connected. The time ofconnection varies according to the shape of the eccentric. This lattermarks one division in twenty-four hours. It is fixed by a screw on theconical end of the shaft. This arrangement permits of easily adjustingthe working of the apparatus.

Having thus described my invention and in what manner the same has to becarried out, what I claim is 1. The combination, with a gas-meter having a mechanism for registering the total consumption of gas, of amechanism for registering a part of the consumption of gas, and meansfor connecting the mechanisms, substantially as described.

2. The combination, with a gas-meter having a mechanism for registeringthe total consumption of gas, of a mechanism for registering the amountof gas consumed at certain times operated by the shaft of thefirst-named mechanism, substantially as described.

The combination, with a gas-meter having a mechanism for registeringthe total consumption of gas, of a second mechanism for registering theamount of gas consumed at certain times, a coupling for connecting theshafts of the mechanisms, and alever for shifting the coupling,substantially as described.

4. The combination, with a gas-meter having a mechanism for registeringthe total con sumption of gas, of a second mechanism for registering theamount of gas consumed at certain times, and mcansfor automaticallyconnecting the mechanisms by gas-pressure, substantially as described.

5. The combination, with a gas meter having a mechanism for registeringthe total consumption of gas, of a second mechanism for registering theamount of gas consumed at certain times, and means for automaticallydisconnecting the mechanisms by gas-pressure, substantially asdescribed.

6. The combination, with the main dial shaft G, of the second dial shaftF, coupling or mud H, lever C, and bell A, substantially as described.
